Application filed. November 15, 1909, Serial No. 528,195.

To all whom it may concern:

Be it known that I, SAMUEL H. TrNsMAN, a citi zcnof the United States ofAmerica, and resident of St. Joseph, county of Buchanan, State ofMissouri, have invented a certain new and useful Improvement inPlanters, of which the following is a speoifioation.

My invention relates to seed-planting machines of the type known aslisters-that is to say, planting machines in which a double mold boardfurrow-opener is combined with seed-dropping mechanism operated by thesupporting wheels of the planter, and in which the corn or other seed isdropped in the furrow made by said furrow-opener as the planter is drawnover the field.

Generally stated, the object of my invention is the provision of animproved and highly efiicient seed-planting machine of the so-calledlister type.

A further object is to provide improved means for raising and loweringthe furrowopener in the frame, and to provide means for giving increasedrigidity to the structure.

These and such other objects as may hereinafter appear are attained bymy invention, as illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a planter embodying the principles of myinvention, the near wheel being removed. Fig. 2 is a top plan view ofFig. 1. Fig. 3 is a longitudinal sectional view through thefurrow-opener. Fig. 4 is a detail of the lever 46 and its connectionwith the axle, taken on line 4:& of Fig. 2. Fig. 5 is a sectional viewtaken on line 55 of Fig. A. Fig. 6 is an enlarged sectional view on line66 of Fig. 1, looking in the direction of the arrows.

Like numerals of reference indicate like parts in the several figures ofthe drawings.

Referring now to the drawings-11 represents a double mold furrow-openerplow mounted on a forwardly extending beam 12. A bail-shaped axle 13 issupported in bail hangers on the frame 15 and on its outer ends aremounted the hubs of the wheels let. On the upper portion of the bailaxle 13 is loosely mounted a bearing casting 13, which is rigidlysecured to the plow beam well toward the rear, the beam being supportedby the bail axle 13. The U-shaped body frame 15 is supported at its rearend by the double caster wheel 16 free to swing or caster from side toside. A spring 17 c011- specification of Letters Patent.

nects an extension or lug 18 on the front of the frame with the beam ofthe furrow-opener, thus assisting in raising it from the ground. Aforked member 19 is mounted on the beam in which is mounted a colter 20adapted to travel ahead of the furrow-opener. The arms of the forkedmember fit on either side of the beam and are slotted as shown at 21,permitting the Vertical adjustment of the colter. A pair of rotarycovering disks 22 are secured to the rear ends of the mold boards of thefurrow-opener and positioned to throw the dirt over the seed droppedfrom the spout 23. A drivers seat 2A is mounted on the rear of the frame15.

Extending upwardly from the frame on either side are supports 25connected at the top by a casting or bearing 26, providing a support forthe hopper 27 provided with any suitable seed-dropping mechanism. Thisseed-dropping mechanism is operated by a horizontal shaft 28 supportedin the bearing 26 and provided with a bevel gear 29 engaging the rotaryplate 30 on the bottom of the hopper. A sprocket wheel 31 is secured tothe other end of the shaft 26 and a spring 32 is supported between thesprocket wheel and a bracket arm 33 extending around from the casting26. A collar 34 is keyed or secured to the shaft, and a slotted arm 35is interposed between the collar and the bracket arm 33. This arm isprovided with a cam face 36, and at its lower end is pivotally connectedwith the beam 12 at 36. A sprocket wheel 37 is secured to a sleeve onthe axle connecting with the adjacent wheel 14. A sprocket chain 38connects the sprocket wheel 37 with the sprocket wheel 31 on the shaft28. It is thus seen that when the planter is traveling with thefurrowopcner in the ground, the bevel gear 29 is operated through themedium of the sprocket wheels and chains above described, and the seedplate is revolved, as clearly shown in Figs. 1 and 6, the seed passingdown through the pipe 38 and into the conductor 39, through the spout 23into the furrow made by the furrow-opener. The conductor 39 is supportedin the yoke end 40 of the cast ing 13% When the furrow-opener is raisedfrom the ground, as shown in Fig. 1, the cam face 36 on the arm 35throws the bevel gear out of engagement with the gear on the seed-plate30, thereby rendering the seeddropping mechanism inoperative. A pair ofconnecting straps 41 are pivotally mounted I is a bail hanger 43terminating at its lower end in a bearing 44 for the axle 13, and at itsupper end in a rack 45. An operating lever 46 is rigidly mounted on theaxle by means of a grooved casting 47, the axle fitting within thegroove 48 and held in place by means of a U-bolt 49. An ordinary springcontainer 50 is mounted on the lever, and the dog 51 thrown into and outof engagement by means of the rod 52. It will thus be'seen that when thelever 46 is thrown out of locking engagement with the rack 45, the beamand furrowopener drops of its own weight and is forced into the ground.This movement is opposed by the spring 17, so when it is desired toraise the furrowopener and the lever 46 is thrown back, the springassists in the raising. The straps or swinging link connections 41 forma flexible connection between the rear of the frame and the beam, andserve in lieu of a second bail, and extendingrearwardly in the samegeneral direction as the rearwardly-extending bail axle gives a degreeof rigidity to the structure not heretofore possessed in implements ofthis character. The single bail extending rearwardly is the principalsupport for the plow, and taken in connection with the link connections,gives a simpler construction and at the same time one as ellicient asthose in which two bails are employed.

I claim In a planter, a U-shaped frame, a rear. 'wardly and upwardlyextending bail axle journaled in a bearing on the forward end portionsof said frame, a beam mounted on said axle and extendlng above saidframe, a

furrow opener attached to said beam, seed droppingmechanism mounted onsaid ffame, a seed spout extending from said seed dropping mechanism toa point to the rear of said furrow opener and attached to said furrowopener, a forwardly and downwardly extending swinging link attached tothe rearend of said frame and the lower end of said beam to steady saidfurrow opener and seed spout, means for rocking said axle downwardly andrearwardly to lower said furrow opener and upwardly and forwardly toraise the same, and an arm connect-ed directly to said beam and providedwith means for automatically connecting and disconnecting the seeddropping mechanism when the furrow opener is lowered and raised.

Signed by me at Chicago, Illinois, this 1st day of November, 1909.
